iPad and Toplap for creating atmospheric computer sounds

I was playing with the Toplap app by Click Nilson on the iPad.

TOPLAPapp is a sonic puzzle based around a virtual machine for sound synthesis. This machine only accepts a few valid instructions, and you control it by placing each command letter within a grid, along with setting some associated parameter sliders. The machine runs through the grid, following the instructions to create the output sounds, which are usually of a somewhat noisy character, hopefully interestingly so. The historical antecedents include instruction synthesis as pionneered at the Institute of Sonology in the 1970s, and the live coding movement, of modifying a running program as it acts. This app is intended for those interested in more experimental sound art, and is in no way a traditional diatonic melody generator. Don't download this unless you are open to stranger computer music sounds.

Be careful of your ears, this app can produce wild sounds at high volume. Program this sound synthesis puzzle machine by dragging letters TOPLAp to the grid; you can also set a parameter for each position via the slider at each slot. The audio engine whizzes through the states many times per second. Press ! to clear the grid, and ? to randomise. No save or load is allowed, to promote improvisation. Live coding engineered by Click Nilson.


Click Nilson emerged from the Swedish algorithmic music scene in the mid 1970s with his groundbreaking piece "An Instructional Game for 1 to many musicians". This piece, whilst entirely unrealiant on digital technologies, formed a key part of the techniques - along with other pioneering artists such as Sol Lewitt and the Alan Turing Five - that formed the basis of what has today become the production of software in a live performative context - i.e., livecoding.

Good stuff man, looks like it could be both useful and fun! The iPad is perfect for this type of thing - if only it was possible to add MIDI to it then it would be a serious music device. Could happen some day though..

yeah! supergame!

looks like fun
